Abstract (en)
[origin: EP0205322A2] Apparatus for controlling the operation of a clutch (2) in a motor vehicle so that the clutch automatically disconnects the gear transmission (6) from the engine (1), comprises pressure sensitive switches (SW1-SW4) which detect the braking force applied to a braking system (12, 12a), and an engine speed sensor (10). Monitored parameters of the braking force, and the engine speed, are fed to a control unit (9) which stores data for comparison therewith. As a result of the comparison, the control unit determines whether the clutch should be rapidly disengaged and, if so, applies a command signal to a clutch actuator (3). Whether or not the clutch is to be rapidly disengaged is preferably ascertained on the basis of a combination of the detected braking force and the detected engine speed, or a detected rate of increase of the braking force, so that the engine is prevented from being stalled as a result of, for example, rapid depression of the brake pedal.
